My favorite "B" vitamin is back in the headlines as a new study confirms that "vitamin booze" is just about the best preservative for brain cells around.

Was there really any doubt?

Researchers looked at data on some 365,000 patients who took part in 143 studies published since 1977 and found that a moderate drinking habit can slash the risk of Alzheimer's disease, dementia, and other forms of cognitive impairment by 23 percent.

There's not a drug in the world that can make that claim -- so you'd think that right about now researchers would finally come to their senses and recommend that nondrinkers start drinking.

"We don't recommend that nondrinkers start drinking," Edward J. Neafsey, one of the authors of the new study, said in a news release.

What are these people so afraid of? Drinking is one of the greatest inventions in the history of civilization.

In fact, the need to harvest grains to make booze appears to be have been the very reason for the creation of civilization -- yet today's namby-pamby docs just refuse to tell people it's OK to go ahead and have a drink or two a day.

Lighten up already!

Ignore them and listen to me instead. In addition to the numerous brain benefits, vitamin booze has been shown to protect the heart, lower stress, and help you live longer, too.

Drinkers are even smarter, which should tell you everything you need to know about the teetotalers.

If you really want to supercharge your gray matter, don't forget the rest of the B vitamins: B6, B12, and folic acid have been shown to slow the brain shrinkage associated with cognitive impairment.

I recommend washing them down with an ice, cold beer.
